7. INFORMATIVE 1: Bats can be found in many buildings, even those that initially appear to be unsuitable or have been subject to a bat survey and found no evidence. Therefore, if any evidence of bats is found on site, work should stop while a bat survey is carried out by an experienced bat worker, and any recommendations made following the survey are undertaken. It should also be noted that as bats are a mobile species and can move into a property with potential access at any time. A further survey may be required if the works are not undertaken within two years. Bats and roosts are protected under the 1981 Wildlife and Countryside Act, the Countryside and Rights of Way Act 2000, and The Conservation of Habitat and Species Regulations 2017 (as amended).
8. INFORMATIVE 2: Work should avoid disturbance to nesting birds. Birds can nest in many places including buildings, trees, shrubs, dense ivy, and bramble/rose scrub. Nesting birds are protected under the Wildlife and Countryside Act 1981 (as amended). The main nesting season lasts approximately from March to September inclusive, so work should ideally take place outside these dates if at all possible. N.B birds can nest at any time, and the site should ideally be checked by a suitably qualified ecologist for their presence immediately before work starts, especially if during the breeding season.
9. INFORMATIVE 3: Consideration should be given to the provision of suitable bat and bird boxes within the new build or adjacent trees in order to increase opportunities for wildlife. Many bat and bird populations have declined dramatically in recent years due to loss of roost, nest and foraging sites as a result of development. However, a variety of bat and bird species use boxes and they can be particularly useful in the urban environment, where natural nesting places can be scarce. Further advice and information can be obtained from the Bat Conservation Trust (BCT), and the Royal Society for the Preservation of Birds (RSPB).
